Reverse Engineering
Computer Aided Design(CAD) has
become more popular, reverse
engineering has become a viable
method to create a 3D virtual model
of an existing physical part for use
in 3D CAD, CAM,CAE or other
software.
The reverse-engineering process
involves measuring an object and
then reconstructing it as a 3D model

Digitization
Digitizing or digitization is the
representation of an object
image, sound, document or a
signal (usually an analog signal)
by a discrete set of its points or
samples.

Computational Fluid Dynamics or CFD is
predicting what will happen, quantitatively, in the
analysis of systems involving fluid flow, heat transfer
and associated phenomena such as chemical reactions
by means of computer based simulations.
The technique is very powerful and spreads a wide
range of industrial and non industrial applications.
What is CFD?

IC Engine
An engine in which combustion takes
intermittent.
Our CFD analysis in IC engine by changing,
1)Various combustion volume ratios ,
2)Ignition time,
3)fuel properties,
4)Emission Test
for both petrol engines and diesel engines heads.

Wind Tunnels
Tool which is used in aerodynamic research to study the
effect of air moving past around solid objects.
Results of wind tunnel can be validate through CFD
techniques so its called manual CFD.
Our design achievement in design of wind tunnels are
subsonic tunnels with high mach number (0.5-0.9) flow rate at
80m/s, supersonic tunnels with storage tank with anechoic
system at mach 2.
Test section design for Industrial requirements .
Perfect Nozzle designs for Subsonic, Supersonic,&
Transonic with variable area design & analysis.

Flow over Autonomous Under water Vehicle
Autonomous Underwater Vehicles (AUV) are free
swimming marine robots that require little or no human
intervention.
AUV are used for commercial, military, research
purpose etc...
Marine propeller is one of the most challenging
problem

Turbine Blade Stress Analysis
Turbine blade is the major part in Aero Domain.
Work of turbine is to convert low pressure to high
pressure and to send hot gases to Nozzle through
Nozzle guide vanes and also to withstand High temp
gas which comes out from Combustion chamber,
Our CFD,FEA analysis on turbine blade is at 36000
rpm with1200‟C temp to choose High temperature
material like Inconel 710,720,Udinet 720,RR 1000,Li
720Ni which is suitable for all conditions.

Fuel Cells
Device which convert chemical energy of fuel to
electrical energy.
Types PEMFC(Polymer electrolyte membrane
fuel cells),SOFC(Solid oxide fuel cells),High temp
electrolysis.
Our CFD analysis on new designs of fuel cells
for Automobile industry PEMFC,SOFC,High

Reliability in the welding of dissimilar metals explosive
welding, particularly in the wake of new welding Thermal
engineering techniques.
The use of an interlayer is proposed for the reduction of
kinetic energy loss and the formation of intermetallic layer
at the interface.
Our analysis an explosive is done through Autodyn for
various detonators ad various metal bonging with and
without interlayer.

Roll Rate of Missile
While free flight missile generate „Adverse roll’
arising from manufacturing asymmetry, small
protrusion,sepration dynamics & unsteady
atmospheric conditions
This problem arise when roll rate is more than
10RPM
Our CFD analysis on missile is to analysis the roll
rate with and without canard configuration to avoid
Adverse roll when it launch from aircraft.

Underground Garage Systems or Car Park are an
innovative idea that provide a unique underground
parking solution.
This car parking system doubles vehicle storage
potential by utilizing space that we already have.
It also adds an extra layer of protection for vehicles
which can potentially lower our insurance premiums.
Underground parking systems are a convenient and
cost effective way.
This may be an ideal solution for a listed building
or where building restrictions are a problem.

Stagnation zone
Initial Fan locations
Suggested Fan location
No Stagnation
Airflow Analysis
Airflow analysis is done to ensure the
optimum number of fans and its
locations ,so that there is no stagnation
inside the car park.

Carbon monoxide (CO) Analysis
Carbon monoxide simulation is done to ensure
the event of a CO high level (>100 PPM [Parts Per
Million] ) is avoided at short term exposure of 30
minutes.

Fire Case Scenario
This is a post fire smoke management
system, thus in the event of fire, there is a
clear view of over 30m from any corner of
the car park to the nearest means of escape
point within 45 minutes, after the fire starts.
From Airflow, CO and Fire conditions,
we can conclude whether the ventilation
system provided is effective or not.

Cyclone Heat Exchanger
Cyclones have been one of the oldest and most popular devices
for the removal of dispersed particles from the carrying gas flow
because of the simple design and ability to operate at high loading.
Determining the holdup mass and the time required by the
particle to reach the bottom of the Cyclone Heat Exchanger using
CFD analysis by varying the size, mass flow rate and position of
solid particles.
Holdup mass is inversely proportional to velocity if velocity
increase holdup mass will decrease.

Aircraft Landing Gear stress Analysis
Landing gear is the most important part of
aircraft.
Many major accidents happen during landing. So
landing gear analysis is most important.
The structural analysis for landing gear is done at
various load conditions applied.
